. z or toTheHooverCompany, North Canton, 7 Ohio, a corporation of Ohio r Application October 22, 1931'. Serial No. 570,280 '6 Claims. (01. 35-12) videa new and improved advertising display de-' vice for a suction cleaner. A still further object is the provision, in advertising display device,

'15 of a construction in'which a human being is lifted by the suction created by a suction cleaner, means being provided to weighthe person lifted. These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawing to whichthey relate.

Referring now to the drawing, which a preferred embodiment of the present invention-is disclosed.

In Figure 1 is disclosed a front view of the advertising display device comprising the present invention.- V

Figure 2 is a partial section looking inthe direction of the arrows upon line2-2 in Figure 1. Figure 3 is a section of the suction-actuated collapsiblechamber in a partially collapsed con dition.

Referring again to the drawing a framework is disclosed which comprises a tripod having three spaced legs, 10, 10, 10. Legs 10, 10, are connected in rigid relationship by means "of a triangular frame comprising cross members 11, 11,

11, the legs 10 of the frame extending above the The upper ends of the legs 10,,

cross members. 10, 10 are bent so as to extend substantially horizontally and are connected, by means of bolts 12, 12 etc. to a collapsible chamber which is indicated generally by the reference character 13 and which comprises an upper rigid side 14, to

which the'bolts 12, 12 are connected, a rigid movable side 15, anda collapsible enclosing side 16 between sides 14 and 15 which may be formed of suitable substantially air proof material and which is itself provided with reenforcing circularv rods 17, 1'7. 7

Suspended from the movable rigid side 15 of the chamber 13, is a scale 18 which supports, through a suitableframework 19, a chair 20, the relationship between the parts being such that with the chamber 13 in the expanded position or relationship the chair 20 is just resting upon'the su porting surface, and the scale 18' indicates azero reaqmg. g Positioned'at the side of the triangular framework',-an'd preferablyin front of the chair 20,

is asuction cleaner which is indicated generally by the reference character 21. This cleaner is a of a well known'type and is connected, by means of an electric'conduit 22, toa source of electric power in orderthat the machinemay be driven to create a suction. Extending between the cleaner 21 andjthechamber 13 is a flexible con-'- duit 23 which, at its cleaner end is connected to the suctionfinlet ofl'the machine and, at its chamber end'gis; connected in sealed relationship with the: interior 'ofthechamber 13 through the rigid wall 14. Enclosing the upper end of the chamber-supporting frame is a suitably formed vertical wall which is indicated by the reference character 24. Wall 24 is provided on its forward face, or that viewed when facing the scale and chair, with suitable instructions as to the purpose of the mechanism or display device. This wall also performs the useful function of covering and hiding from the observers the comparatively unsightly chamber which is positioned therebehind. r

In the operation of a display device constructed in accordance with the present invention the chamber supporting frame is positioned in a preferably open space where it can be readily observed. The suction cleaner is connected, by means of its electric cord 22, to a source of power and is positioned preferably in front of thechair 20 in order that the occupier thereof must, of 9 necessity, be aware of its presence. The operator ofthe display device turns on the electric cleaner motor thereby causing a reduced pressure to be created therein which functions to draw air through the hose 23 and from the chamber 13. The party to be weighed sits in the chair 20 in anordinary manner and, as the air within the chamber 13 is withdrawn, the movable side 15 thereof is lifted upwardly or, more accurately, is forced upwardly by the greater exterior pressure. As the movable side-15 moves upwardly the reading upon the scale 18 increases until the correct weight of the occupant of the chair is indicated at which time the chair will be lifted, together with its occupant, from the supporting surface and he will, of necessity, become aware of the fact, as willall observers, that the suction cleaner, which is operating before him, has lifted him from the floor. To return the device to initial position it is only necessary to disconnect the i observer in an impressive manner the suction power of the suction cleaner which is-before him and which makes possible his being weighed and his being lifted from the supporting surface.

Iclaim: I 1. In an advertising display device, a collapsible chamber having a rigid movable side,.means supporting said chamber above a supporting sur face, a seatsuspended from the movable side of said chamber, and a suction-creating' device comprising a suction cleaner positioned near said'seat connected to and adapted'to collapse said chamher for the purpose of lifting said seat in order to show the suction'powe'r of said cleaner.

2. In an advertising'display device, a collapsible chamber having a rigid movable side, means supporting said chamber above a supporting surface, a scale suspended from-the movable side of said chamber, a seat suspended from said scale, and means to collapse said chamberto lift said scale andsaidseat. f

3. In an advertising, display device, a collapsible chamber having a rigid movable' side, means supporting said chamber-above a supporting surface,

ascale suspended from the movable side of said chamber, a seat suspended from said scale, and means to collapse said chamber to lift said scale and said seat comprising a suction cleaner.

4. In an advertising display device, a collapsible chamber having a rigid movable side, means supporting said chamber above a supporting surface, a scalesuspended from the movable side of said chamber, a seat suspended from said scale and touching the supporting surface with the chamher in the expanded position, and a suction cleaner connected to said chamber adapted to draw air therefrom to collapse said chamber to lift said scale and chair.

5. In an advertising display device, expansible and contractible means interior-1y sealed from the atmosphere, visible object-carrying means supported by a movable part of said first mentioned means, and a visible suction cleaner connected to said first mentioned means to exhaust air therefrom to lift said object-carrying means for the purpose of illustrating the'suction power of said suction cleaner. K

6'. In an advertising display device, expansible and contractible means interiorly sealed from the atmosphere; a support holding said means above a supporting surface, a visible scale carried by 'a movable part of said means, a'visible chair carried by said scale and positioned within the COD-r fines of said support, a visible suction cleaner adapted to create a reduced pressure, and means connecting said expansible and contractible means to a low pressure point of said suction cleaner.
